Err, sure. but it requires all applications to be rebuilt that used to
use the internal function ff_gcd. Other applications do use that

Which has consequences for applications using it.

(and therefore testers) indicate interest, I don't want to go that
way. Especially since the other way I indicated would be much safer,
